CentOS 7 Apache (httpd) 설치

 

Linux 서버에서 웹서비스를 하기 위해 가장 많이 사용되는 웹서버는 Apache (httpd) 이다.

(apache 라는 이름이 2.x 버전으로 접어들면서 httpd 이름으로 배포되기 시작하였다)

웹서버를 설치하면 브라우저상에 IP 또는 도메인 주소를 입력하여 사용자가 만들어놓은 웹페이지를 띄울 수 있다.

이를 이용하면 회사 소개 홈페이지를 띄울 수도 있으며 상품 홍보를 하거나 커뮤니티 사이트를 운영하거나

스트리밍 모듈을 추가하여 영상을 재생 시키는 등의 서비스가 가능하다.

 

아래는 CentOS7 환경에서 httpd 2.4.54 버전 prefork으로 설치를 진행 하였다.

 

Apache 설치


  

1. 필수 구성요소 설치

 

# yum install -y vim wget epel-release

# mkdir -p /usr/local/src/APM_Setup

# yum install -y https://rpms.remirepo.net/enterprise/remi-release-7.rpm

# ln -s /usr/lib64/libXpm.so.4 /usr/lib/

# ln -s /usr/lib64/libXpm.so.4.11.0 /usr/lib/

 

2. default 환경변수 설정

# echo " " >> /etc/profile

# echo "####default PATH#####" >> /etc/profile

# echo "export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:" >> /etc/profile

# echo "#####################" >> /etc/profile 

 

 

3. Apr 설치

# cd /usr/local/src/APM_Setup

# wget https://archive.apache.org/dist/apr/apr-1.7.0.tar.gz

# tar zxvf apr-1.7.0.tar.gz

# cd apr-1.7.0

# ./configure --prefix=/usr/local/apr

# make -j

# make install

 

4. Apr-iconv 설치

cd /usr/local/src/APM_Setup

# wget https://archive.apache.org/dist/apr/apr-iconv-1.2.2.tar.gz

# tar zxvf apr-util-1.2.2.tar.gz

# cd apr-util-1.2.2

# ./configure --prefix=/usr/local/apr --with-apr=/usr/local/apr/bin/apr-1-config

# make -j

# make install 

 

5. Apr-util 설치

# cd /usr/local/src/APM_Setup

# wget http://mirror.apache-kr.org/apr/apr-util-1.6.1.tar.gz

# tar zxvf apr-util-1.6.1.tar.gz

# cd apr-util-1.6.1

# ./configure --prefix=/usr/local/apr --with-apr=/usr/local/apr/bin/apr-1-config --with-apr-iconv=/usr/local/apr/bin/apriconv --with-crypto --with-openssl --with-nss --with-lber --with-ldap --with-ldap-include=/usr/include --with-ldap-lib=/usr/lib64/

# make -j

# make install 

 

6. pcre 1 설치

cd /usr/local/src/APM_Setup

# wget https://ftp.exim.org/pub/pcre/pcre-8.45.tar.gz

# tar zxvf pcre-8.45.tar.gz

# cd pcre-8.45

# ./configure --prefix=/usr/local/pcre --enable-pcre8 --enable-pcre16 --enable-pcre32 --enable-jit --enable-utf8 --enable-pcregrep-libz --enable-pcregrep-libbz2 --enable-pcretest-libreadline --enable-valgrind

# make -j

# make install 

 

7. httpd 설치

# cd /usr/local/src/APM_Setup

# wget https://archive.apache.org/dist/httpd/httpd-2.4.54.tar.gz

# tar zxvf httpd-2.4.54.tar.gz

# cd httpd-2.4.54

 

동시 접속자 수 변경

# vi server/mpm/prefork/prefork.c

# define DEFAULT_SERVER_LIMIT 256 기존값 256에서 2048로 변경해준다. 동시접속이 2048개 접속이 가능하다.

 

아래는 vi로 수정할 필요 없이 sed로 내용을 치환해서 수정합니다.

sed -i "s/#define DEFAULT_SERVER_LIMIT 128/#define DEFAULT_SERVER_LIMIT 2048/g" ./server/mpm/prefork/prefork.c ← 기존값 256에서 2048로 변경해준다.
sed -i "s/#define DEFAULT_SERVER_LIMIT 16/#define DEFAULT_SERVER_LIMIT 32/g" ./server/mpm/worker/worker.c ← 기존값 16에서 32로 변경해준다. 32 * 64 = 2048
sed -i "s/#define DEFAULT_SERVER_LIMIT 16/#define DEFAULT_SERVER_LIMIT 32/g" ./server/mpm/event/event.c ← 기존값 16에서 32로 변경해준다. 32 * 64 = 2048

 

* 여기서 sed 라는 명령어는 파일들을 출력, 치환 및 변경해줄 수 있는 명령어이다.

 

# ./configure --prefix=/usr/local/apache --enable-load-all-modules --enable-maintainer-mode --enable-debugger-mode --enable-pie --enable-modules=all --enable-mods-shared=all --enable-imagemap --enable-authnz-ldap --enable-authnz-fcgi --enable-allowmethods --enable-isapi --enable-file-cache --enable-cache --enable-cache-disk --enable-cache-socache --enable-socache-shmcb --enable-socache-dbm --enable-socache-memcache --enable-socache-redis --enable-so --enable-rewrite --enable-ssl --enable-expires --enable-proxy-fcgi --enable-proxy-scgi --enable-proxy-html --enable-cgi --enable-cgid --enable-xml2enc --enable-cern-meta --enable-case-filter --enable-ident --with-apr=/usr/local/apr/bin/apr-1-config --with-apr-util=/usr/local/apr/bin/apu-1-config --with-pcre=/usr/local/pcre/bin/pcre-config --with-mpm=prefork --enable-http --disable-http2 --enable-modules=all

# make -j

# make install

 

 8. mod_url 설치 및 연동 ( 한글파일명 파일 인식 ex: 업로드.html )

# cd /usr/local/src/APM_Setup

# wget https://kldp.net/modurl/release/2188-mod_url-apache2-1.25.tar.bz2

# tar xvf 2188-mod_url-apache2-1.25.tar.bz2

# cd /usr/local/src/APM_Setup/mod_url-apache2-1.25

# /usr/local/apache/bin/apxs -iac mod_url.c

# echo "" >> /usr/local/apache/conf/httpd.conf

# echo "
CheckURL On
ServerEncoding EUC-KR
ClientEncoding UTF-8
" >> /usr/local/apache/conf/httpd.conf

# echo "" >> /usr/local/apache/conf/httpd.conf

 

 9. httpd.conf 설정파일 수정

sed -i "s/`grep '^User ' /usr/local/apache/conf/httpd.conf`/User nobody/g" /usr/local/apache/conf/httpd.conf

sed -i "s/`grep '^Group ' /usr/local/apache/conf/httpd.conf`/Group nobody/g" /usr/local/apache/conf/httpd.conf

sed -i 's/#ServerName www.example.com:80/ServerName localhost:80/g' /usr/local/apache/conf/httpd.conf

sed -i 's/DirectoryIndex index.html/DirectoryIndex index.html index.php index.jsp/g' /usr/local/apache/conf/httpd.conf

sed -i 's/ServerAdmin you@example.com/ServerAdmin root@localhost/g' /usr/local/apache/conf/httpd.conf

sed -i 's/#AddHandler cgi-script .cgi/AddHandler cgi-script .cgi/g' /usr/local/apache/conf/httpd.conf

sed -i '/AddType application\/x-gzip .tgz/a\ #PHP Enable' /usr/local/apache/conf/httpd.conf

sed -i '/\ #PHP Enable/a \ AddType application/x-httpd-php-source .phps' /usr/local/apache/conf/httpd.conf

sed -i '/\ #PHP Enable/a \ AddType application/x-httpd-php .php .jsp .html .inc ' /usr/local/apache/conf/httpd.conf

 

home Web source file 설정 

일반적으로 /home/일반계정/웹소스파일 이렇게 있기 때문에 해당 설정을 넣는다.

echo "" >> /usr/local/apache/conf/httpd.conf

echo "
AllowOverride All
Options Indexes FollowSymLinks
Require all granted
" >> /usr/local/apache/conf/httpd.conf

echo "" >> /usr/local/apache/conf/httpd.conf

 

 

10. 자동 실행 설정

# cp -arp /usr/local/apache/bin/apachectl /etc/init.d/

# chmod 700 /etc/init.d/apachectl 

# sed -i '/#!\/bin\/sh/a # chkconfig: 2345 90 90' /etc/init.d/apachectl

# sed -i '/#!\/bin\/sh/a # description: init file for Apache server daemon.\' /etc/init.d/apachectl

# sed -i '/#!\/bin\/sh/a # processname: /usr/local/apache/bin/apachectl' /etc/init.d/apachectl

# sed -i '/#!\/bin\/sh/a # config: /usr/local/apache/conf/httpd.conf' /etc/init.d/apachectl

# sed -i '/#!\/bin\/sh/a # pidfile: /usr/local/apache/logs/httpd.pid' /etc/init.d/apachectl

 

11. 부팅시 자동실행 설정

# chkconfig --add apachectl

# chkconfig --level 3 apachectl on

 

 

12. APM 환경변수 설정

# echo " " >> /etc/profile

# echo "APACHE_HOME=/usr/local/apache" >> /etc/profile

# echo "MySQL_HOME=/usr/local/mysql" >> /etc/profile

# echo "PHP_HOME=/usr/local/php" >> /etc/profile

# echo " " >> /etc/profile

# echo "export PATH="\$"APACHE_HOME/bin:"\$"MySQL_HOME/bin:"\$"PHP_HOME/bin:"\$"PHP_HOME/sbin"\$"{PATH:+:"\$"{PATH}}" >> /etc/profile

# echo " " >> /etc/profile

# source /etc/profile
